<p dir="auto">Hi Levente and All,</p>
<p dir="auto">Just wanted to pass on some information about EPOLL and Linux.</p>
<p dir="auto">We were working on sharing our applications through RFB but were having an<br>
issue where keyboard input created a change on the remote window but the<br>
changes were not showing up.  You could see the issue with a simple browser<br>
doing a web search on google and pressing enter.  The screen froze but if<br>
you clicked with a mouse or created any other event the changes showed up.<br>
Eliot suggested the issue could be with EPOLL not signaling the semaphore<br>
properly when data was available on the socket.  After Eliot created a new<br>
EPOLL-less linux vm the problems went away.  There does appear to be an<br>
issue with EPOLL on linux.</p>
<p dir="auto">All the best,</p>
